Reading from fstream into vector

[D. Susman]

Hi,

In the code snippet below, I am trying to read the contents of a file
into a vector. However I can't get it compiled. I am using Sunstudio
which compiles C++ using cc.

Here is the code:

#include <fstream>
#include <vector>

int main( int argc, char ** argv )
{
std::ifstream input( "input.txt" );
std::istream_it erator<intdataB egin( input );
std::istream_it erator<intdataE nd;
std::vector<int v( dataBegin, dataEnd ); //Compiler error

return (EXIT_SUCCESS);
}

Compiler error: Could not find a match for
std::vector<int >::vector(std:: istream_iterato r<int, char,
std::char_trait s<char>, int>, std::istream_it erator<int, char,
std::char_trait s<char>, int) needed in main(int, char**);

Anyway, the absence of the <iteratorshould n't come out such compile
time error, it's helpless

Might try (tested):

#include <iterator // stream_iterator
#include <vector>
#include <fstream>
int main(){
std::ifstream input( "input.txt" );
std::vector<int data;
std::copy(
std::istream_it erator<int>( input ),
std::istream_it erator<int>(),
std::back_inser ter( data ) );
}

You need to include <iteratorfor std::istream_it erator.

You need to include <iteratorfor std::istream_it erator.

Thanks for the advice, but it still does not compile. I think it's
something about the CC compiler. With g++ 3.4.3, the compiles just
fine.

What can it be about CC which refrains the code from being compiled?

Thanks, that is where I am just heading to.
